S-8201 Datasheet | Seiko Instruments

Features (1) Internal high accuracy voltage detection circuit - Overcharge detection voltage 3.9 V to 4.4 V (5 m V step), Accuracy ±25 m V (+25 °C), ±30 m V (- 5 °C to +55 °C) - 1 - Overcharge release voltage 3.8 V to 4.4 V , Accuracy ±50m V - Overdischarge detection voltage 2.0 V to 3.0 V (10 m V step), Accuracy ±50 m V - 2 - Overdischarge release voltage 2.0 V to 3.4 V , Accuracy ±100 m V - Overcurrent 1 detection voltage 0.05 V to 0.3 V (10 m V step) Accuracy ±15 m V - Overcurrent 2 detection voltage 0.5 V (fixed) Accuracy ±100 m V (2) High voltage device is used for charger connection pins. (VM pin and CO pin: Absolute maximum rating=28 V) (3) Delay times (Overcharge: t CU, Overdischarge: t DL, Overcurrent 1: tl OV1, Overcurrent 2: tl OV2) are generated by an internal circuit. (No external capacitor is necessary.) Accuracy ±20% (4) The overcharge timer reset delay time (7 ms to 40 ms) is generated by an internal circuit only. (No external capacitor is necessary.) (5) Three-step overcurrent...
